and to the letters and figures of reference marked thereon. l A lhe object of the present invention 1s to provide ari ng, sheet, gasket-or other like paoking used in steam, oil, water, and other joints whereby a perfectly tight jolnt under a very light pressure is obtained, thereby enabling the user of said packing to remove the same trom the joints and again use them on other joints thus creating a great saving where many joints are to be packed.

lt has been the custom heretofore to screw the joint u i so tight in order to obtain the desired y result, that the packing would be pressed out of shape and could not be used in any other joint, and when a new joint was necessary to be made, the old packing was thrwn away and a new one used to take its place.

It has been found that a raised ,ring or l lange or bead taking the same line in a circle around the edge ofeach bolt hole will allow the metal flanges when brought together on the surface of the gasketor packing to form a tight joint under very light pressure without defacing or injuring in any way the face of the gasket orpaeking.

The invention consist oi' a gasket or other packing of comprussiblc material constructed substantially as shown in the drawings and hereinafter described and claimed.

Figure 1 ol the drawings is a plan view of a gasket or packing .constructed 1n accordance with my invention. tion taken on line 2 2 of Fig. 1.

vThe awompanying drawings represent a gasket o1' other like packing Aformed of a suit' able compressible, elastic, or flexible material having in the present instance the usual bolt-holes al) and the central opening Fig. 2a sectional elevac. Around the -bolt-holes a b are roundcircular rejections d which take the same line in a circ e around said boltholes, and if desired a similar projection e may encircle the outer edge of the gasket or packing and also a projection f around the central opening c. These projections conforming to the circular bolt-holes around the same or taking' the same line in a circle around the edge thereof will admit of the metal flanges when brought together on the surface ofthe gasket or packing to form a erfectly tight joint with comparatively'litt e pressure.

Gaskets or packing of any suitable material may be used as the essential feature of the invention resides 1n the round circular projections around the bolt-holes without regard to the material from which the packing is formed. Having now fully described my invention,

what I claim as new and desire to secure by Letters Patent is 1. As an improved article of manufacture, a gasket or packing ina single integral element having bolt holes therein and a single projection encircling each hole, said projection taking the same line in a circle around the edge and at a distance from each hole.

2. As an improved article of manufacture,

a gasket or packing in a single integral ele-l ment having bolt holes therein and a single projection encircling each hole, said projection taking the' same line in a circle around the edge and at a distance from each other, and a similar` projectionencircling the outer edgeof the gasket or packing.

3. Asan improved article of manufacture, a gasket or packing in a single integral element having bolt holes therein and a single projection encircling each hole, said projection taking the same line in a circle around th'e edge and at a distance from each hole, said projections being rounded.

In testimony-whereof I aix my signature in presence of two witnesses.
